alsa-project/alsa-ucm-conf issue #55 was opened from deponian:

Hello. Yesterday I have upgraded Arch Linux on my laptop with `pacman -Syu` and after reboot I've had no sound from built-in speakers. I had downgraded all upgraded packages and started upgrading one-by-one with reboot after every step. I have found out that upgrading `alsa-ucm-conf` package from `1.2.3-2` to `1.2.4-1` is causing the issue. If I understand correctly my laptop has something called `Family 17h (Models 10h-1fh) HD Audio Controller` which is using for output and `Raven/Raven2/FireFlight/Renoir Audio Processor Stereo` which is using for input. After upgrading to `1.2.4` I had had only broken output, the input (microphone) was working correctly. I have attached two outputs of `alsa-info.sh` to this message: one before and other one after upgrade. [alsa-info-1.2.3.txt](https://github.com/alsa-project/alsa-ucm-conf/files/5403794/alsa-info-1.2.3....) [alsa-info-1.2.4.txt](https://github.com/alsa-project/alsa-ucm-conf/files/5403796/alsa-info-1.2.4....) I hope it will help.
